“…Since the first study of polymerizable surface-active agents in 1956, a broad range of polymerizable surfactants have been prepared and evaluated. Polymerizable moieties incorporated within surfactants include styrenic, maleate, − (meth)acrylic, , allyloxy, and crotonate groups. The polar head groups of these surfactants may be charged (anionic, cationic) or nonionic and include hydrophilic groups such as sulfonate, , sulfate, , maleate, , carboxylic acid, ammonium, methyl sulfate, PEO (poly(ethylene oxide)), ,, amido esters, and others.…”

“…The polar head groups of these surfactants may be charged (anionic, cationic) or nonionic and include hydrophilic groups such as sulfonate, 2,3 sulfate, 11,12 maleate, 4,5 carboxylic acid, ammonium, 12 methyl sulfate, 6 PEO (poly(ethylene oxide)), 9,14,15 amido esters, 10 and others. By using polymerizable surfactants instead of their nonreactive counterparts, improvements in corresponding latex film properties often result, including stability against low temperatures 5,14 and electrolytes, 3,9,11 water resistance, 7,11,14 and mechanical resistance. 7 Desired characteristics of polymerizable surfactants are as follows: 16,17 (i) providing effective surface properties and emulsification activity that stabilizes latex particles during emulsion polymerization; (ii) having proper polymerization reactivity below that of monomers within the particles so polymerizable surfactants are not consumed prematurely so they are buried within particles; and (iii) obtaining a large fraction of the surfactant molecules covalently linked and located at the latex surface upon completion of the polymerization, leaving minimal unreacted surfactant remaining in the aqueous phase.…”

Biobased ω-hydroxytetradecanoic acid prepared via an efficient yeast-catalyzed ω-hydroxylation reaction was converted by a onestep reaction to the polymerizable surfactants ω-acryltetradecanoic acid (MA-1) and ω-maleate tetradecanoic acid (MA-2). MA-1 is a single polarheaded surfactant, whereas MA-2 is a bolaamphiphile with carboxylic acid polar groups at both chain ends. MA-1 gave a distinct critical micelle concentration (cmc) at 253 mg/L, whereas for MA-2, the surface tension decreased monotonically and a distinct cmc was not observed even up to 1800 mg/L. Experimental determination of the reactivity ratios for MA-1 and MA-2 with styrene showed that for MA-1 copolymers that approximate random structures were formed while MA-2 tends to form copolymers with an alternating nature. Emulsion polymerizations conducted with varying amounts of MA-1 and MA-2 (1−10 wt % with respect to styrene) gave colloidally stable latexes with particle sizes ranging from 52 to 155 nm. In emulsion polymerizations using either MA-1 or MA-2 at more than 5 wt % to monomer, a linear increase in latex particle volume with conversion was observed and the particle number remained constant, establishing that the polymerizations proceeded without significant aggregation or secondary particle nucleation. Potentiometric titration and 1 H NMR were used to measure MA-1 and MA-2 conversions during polymerization as well as how the surfactants were distributed between the particle surface, aqueous phase, and particle interior. Observed differences were rationalized based on the comparative structures of MA-1 and MA-2 and their corresponding partitioning behavior.

Novel surface active maleate and methacrylate monomers based on derivatives of ω‐hydroxy carboxylic acids have been synthesized. The monomers are comprised of hydrophobic alkyl chains and hydrophilic poly(ethylene glycol), quaternary ammonium, sulfonate and carboxylic fragments. Synthesized monomers sufficiently reduce surface tension at the aqueous solution‐air interface. The copolymerization of synthesized monomers with 5‐tert‐butylperoxy‐5‐methyl‐2‐hexene‐3‐yne monomer and N‐vinylpyrrolidone in solvent and emulsion copolymerization of synthesized peroxide containing surface active monomer with styrene have been carried out. The synthesized surface active monomers have been shown to be suitable emulsifiers for obtaining polystyrene colloid dispersions. It has been ascertained that the surface active copolymers obtained can form stable interpolyelectrolyte complexes with oppositely charged polymers.

The interaction of ε-caprolactone with tertbutylhydroperoxide led to tert-butylperoxyhexanoate. Peroxymaleinate has been obtained by the reaction of tert-butylperoxyhexanoate with a maleic anhydride. Functional monomers have been synthesized by reactions of peroxymaleinate with propansultone and polyethylene glycol (PEG). The obtained compounds exhibit surface active properties, reducing a surface tension at the water-air interface.
